(Cl. ca-196) This invention relates to combined clothes washing and-rinsingmachines and has for its general object to provide means whereby awashing machine structure may be utilized in an economical and emcientmanner forenabling the 5 clothes to berinsed therein andremovedtherefrom afterthe conclusion of the washing operation. In myPatent No. 2,161,022, issued June 6, 1939, there are shown, describedand claimed a means for enabling a washing machine of one type ofstandard construction to be utilized as a rinsing machine and whereinthis result is accomplished by suspending a perforated cover within thetop of the tub of a washing machine, wherein the cover is provided withacentral opening to permit the top of the rotor to extend therethrough,and the body of the tub is provided with an overow located above thesaidMy invention herein has for one of its more 20 limited objects toprovide the tub of a Washingmachine with rinsing means including a coverelement having a perforated bottom portion and which cover element isremovably applied to the top of the tub and wherein the perforatedportion of the bottom is provided with means for effectively handlingand of the soapy water contained in the clothing after the precedingwashing operation.

A further object of my invention is to provide a cover element of thistype with means whereby substantially all of the liquid which may bepassed through the perforations of the bottom portion of the same may be.quickly and coning operation. I accomplish the foregoing .objects inand throughthe construction and arrangement of parts shown in theappended drawing,wherein Fig. l represents a central vertical sectionportion of a washlngmachine embodying my invention; the. rotor beingshown in elevation; and Fig. 2 a detail in section taken ontheline2-2ofFig.1. fj V l I Describing the construction and arrangement 45 ofparts shown in the said drawing, I denotes the of standardconstrucbottom 2 on a support- `tion, the same having aA ing base 3, andprovided at its top with an' open outwardly concave around. l l

and as such tion of the lsame are unnecessary thetub, the same beingIprovided with a valve 8. The construction and arrangement of all of theforegoing parts are those employed in a well known type of washingmachine and need .no further description.

In orderl to convert the machine thus shown and described into-aneffective rinsing machine, I have provided the following construction: 9denotes a cover element, the same having a top wall III, a perforatedbottom wall Il. and a side wall I2. Extending from. said cover elementabove the bottom thereof is a wide outwardly and. downwardly extendingdischarge spout I3, the same having its delivery outlet Il located belowthe top of the tub and below the perforated bottom II.V Adjacent to itslower end, the cover element is provided with a. flange I5 providing.with the portion of the side therebelow a downhaving a gasketvi seat isextended downwardly below the bottom II to provide an annular rim I1which fits within the bead 4. j

The cover element may be secured in place by means of ahook I8 locatedbeneath the central and by one or more hooks adapted to be swung intoengagement with the outer downwardly and outwardly-extending edge of thebead 4, each of said hooks being adapted to be operated by a lever shownas oomprising side members lower ends of the side members are .mountedupon a` shaft 2l extending through lugs 22 projecting upwardly from thechannel iiange I5 and the upper ends of the said side members areconnected by a pin 23 mounted therein with the "upper end of the hook 24the lower end of which to be swung beneath-and engage the end of thebead I when the lever is shown in Fig. 1. Asstated, more than one ofthese locking membersV II-2I may be' provided for the cover element, ifdesired. Inaddition, the cover element is provided with handles 25 topermit its application to or removal l tub. The bottom I I of the coverelement is a plate provided with upwardly tapered openings 26 and withradial ribs 21 and concentric circular ribs 28, the rim I1 constitutingthe outermostlof the said concentric ribs.

Adjacent to the spout I3, the bottom is depressed to form a sump 29,preferably oval in outline, with its longer axis transverse of the axisof the spout. 'I'he said sump is provided with upwardly taperingopenings 3U in the extreme bottom thereof and with upwardly and inwardlytapering openings 3l extending entirely about and through the wall ofthe sump intermediate the bottom and the top thereof. Between the seriesof openings 30 and 3I, the downwardly and outwardly extending ribs 32are located.

The bottom of the sump thus described cooperates with the remainder ofthe bottom of the cover element in providing for the delivery of rinsingwater therethrough, while the ribs on the sump as well as those on theremainder of the cover element prevent the articles being rinsed frombeing forced into engagement with the portion of the bottom intermediatesaid ribs and from clogging the openings therethrough. In addition, andat the conclusion of the rising op-4 eration, the sump provides part ofthe means for effecting speedy removal of any water which may tend toremain below the bottom of the receiving end of the spout, both abovethe bottom of the cover element and within the top of the tub to thelevel ofthe bottom of the tube within the sump. Cooperating with thesump is a Siphon tube 33 having its inner end in close proximity to thedepressed central portion of the sump and extending through and belowthe spout I3 and having its lower end located a distance below the saidsump and provided with a valve 34. 'I'he provision of the two series ofopenings 30 and 3I in the sump is for the purpose of securing an amplesupply of liquid to the sump at all times until the lower end of thesiphon tube is unsealed. With the parts constructed and arranged as ydescribedfthe operation will be readily understood. The water forwashing the clothes or other articles may be placed in the tub in theusual manner, orsupplied through the drain connection 1 by slippingoverthe end .thereof a hose 35 having at its opposite end a faucet 36. Afterthe tub has been filled, for washing purposes and soap added thereto,the rotor 5 will be operated to agitate the articles in the soapy waterin the tub. The clothing may then be removed and one or more new batchesadded and washed with' the same water.

At the end of the washing operation, the soapy water will be withdrawnthrough the drain connection. The clothing which has been washed will bewrung to remove excess dirt and soapy water therefrom, after which thebatches will be put into the tub and each batch treated as follows: Thecover element 9 will be applied to the top of the tub by rst engagingthe hookfl`84 beneath thebead I, as'shown, and thereafter moving thecover downwardly to its seat upon the top of the said bead and bylocking the operating lever (or levers) I9, 20 in the manner describedto lock the other portion of the cover element in place. Water'forrinsing purposes may then be supplied tothe tub while the rotor isoperating. This will enable the water to pass in contact with andthrough the batch of clothing to be rinsed as the latter are beingagitated bythe rotor and the soap or any sediment which may still remainin these articles will be completely removed therefrom, the watercontaining the soap and sediment being delivered through the waste pipeI3. The shape of the openings 23, 30 and 3l enables the soap to becollected about the edges thereof and the combination of the radial andcircular ribs provides traps for the soapy water which prevents thelatter from sloshing around and retarding the rapid delivery of thesoapy water from the articles and from thetub.

At the conclusion of the rinsing operation, the valve 36 will be closedand the valve 34 opened, and any water that may be within the machineabove the perforated bottom and also below the said bottom to the levelof the bottom of the inner end of the siphon tube will be withdrawnthrough the latter. This will enable the operator to disengage the coverelement from the tub and remove the cover without liability of spillingwater upon herself; also, because the water will have been withdrawnbelow the top of the tub by the action of the siphon tube, the operatorwill be enabled to remove the clothing from the tub without liability ofspilling water over the top of the latter and upon herself. The ribs 32which substantially surround the openings 30 and 3| prevent theseopenings from being clogged by the articles of clothing in the upperportion of the tub.

Having thus described my invention, what I claim is:

l. A removable cover element for the tub of a machine of the characterdescribed, the said cover element having a side wall and a perforatedbottom wall below-the top of said side wall, the said cover beingprovided with a discharge outlet communicating with the space above saidbottom wall, the said bottom wall having a sump extending therebelow andadapted to communicate with the space thereabove and provided with oneor more openings communicating with the` space therebelow, and a siphontube having an upper receiving end located within said sump below theportion of the bottom wall thereabove and extending through'the sidewall'of the cover and having its lower delivery end located below itsinner receiving end and provided with a valve.

2 The cover element recited in claim 1, wherein the said openings in thesump are provided with downwardly extending ribs adjacent to the saidopenings.

3. The cover element recited in claim 1, wherein the said dischargeoutlet is anv outwardly and downwardly extending discharge spout, andwherein the said siphon tube extends through the saidspout and has itsdelivery end located therebelow.
